David Durham's Gear Puzzle is a simple puzzle game featured in our
flash design competition. As the game begins, a small blue
character with big puppy-dog eyes catches sight of a pink character
locked in a cage. The cage is chained to a gear suspended from the
top of the screen. Pegs line the wall and various sized gears are
scattered around. Helpless but heroic, the blue guy does the only
thing he can to help: jumps on the gear across the room and starts
spinning it. Your job is to arrange gears on the pegs to transfer
the motion across the room to lower the cage.
